Hazardous Waste Categories

Once a waste has been classified as a hazardous waste, it seems like the job is done, right? Not exactly. Once identified as a hazardous waste, it also is important to know what category of hazardous waste it belongs to:

The category dictates:

  • Land disposal restrictions
  • Treatment standards
  • Generator fees
  • Disposal fees

The hazardous waste category also dictates DTSC’s discretionary authority for variances, hazardous waste management requirements, and whether tiered permitting may apply to the hazardous waste.
